High-Tension Cord Inspection
Measure resistance of high-tension cord (1) by using
If resistance exceeds specification, replace high-tension
High-tension cord resistance
No.1 cylinder high-tension cord resistance: 1.4 – 4.0
No.3 cylinder high-tension cord resistance: 0.6 – 2.0
Spark Plug Removal and Installation
1) Remove air cleaner assembly with air intake pipe
and cylinder head upper cover.
2) Pull out high-tension cords by gripping their caps
and then remove ignition coil assemblies referring to
"Ignition Coil Assembly (Including Ignitor) Removal
3) Remove spark plugs.
1) Install spark plugs and tighten them to specified
Spark plug: 25 N·m (2.5 kgf-m, 18.0 lb-ft)
2) Install ignition coil assemblies referring to "Ignition
Coil Assembly (Including Ignitor) Removal and
3) Install high-tension cords securely by gripping their
4) Install cylinder head upper cover and air cleaner
assembly with air intake pipe.
Spark Plug Inspection
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
• Do not clean or adjust gap for the iridium /
platinum spark plugs.
Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace it with
specified new plug.
For iridium / platinum spark plugs, replace it with new
Spark plug air gap "a"
: 1.0 – 1.1 mm (0.040 – 0.043 in.)
Spark plug type
NGK: BKR6E-11 (Nickel) / IFR6J11 (Iridium)
DENSO: K20PR-U11 (Nickel)
NGK IFR6J11 is highly recommended for
better engine starting performance under –25
°C (–13 °F).
